  • Patent number: 10655274
    Abstract: A threadlike metallic or metallized reinforcer, for example a thread, film, tape or cord made of carbon steel, at the periphery of which is positioned a layer of metal referred to as “surface metal” chosen from copper, nickel and copper/nickel alloys, is characterized in that this surface metal layer is itself coated, at least in part, with at least one layer of graphene; preferably, there is grafted, to this graphene, at least one functional group which can crosslink to a polymer matrix. This reinforcer of the invention is effectively protected from corrosion by virtue of the graphene present at the surface; advantageously, it can be adhesively bonded directly, without adhesion primer or addition of metal salt, to an unsaturated rubber matrix, such as natural rubber, by virtue of the possible functionalization of this graphene.

  • Patent number: 10465273
    Abstract: A process for depositing, with forward progression, graphene on the surface of a metallic or metallized continuous reinforcer, at the periphery of which is positioned a layer of surface metal chosen from copper, nickel and copper/nickel alloys, comprises at least one stage of flame spray pyrolysis (“FSP”), under a reducing atmosphere, of a carbon precursor which generates, in the flame, at least one carbon-based gas such as carbon monoxide which is sprayed onto the surface of the reinforcer in forward progression, and is decomposed thereon to form one or more graphene layers at the surface of the surface metal; an additional stage of graphene functionalization makes it possible to adhere the reinforcer to a polymer matrix such as rubber.
